I used to be a civil servant exam candidate. Life was hardly glamorous, but at least it was mine. Then one morning, I bolted awake in a rundown motel room, only to see someone else's face in the mirror. Turned out I was three years in the past, possessing the body of a boy who just tried to end his own life. Before I could wrap my head around it, a game window popped up in my vision, ordering me to become a K-pop idol... or die.
